H EATING-STOVE.

SPECIFICATION forming part of Letters Patent No. 606,048, dated June 21, 1898. Application filed October 11, 1897. Serial Ila 654,907. (No model.)

To aZZ whom it may concern:

Be it known that I, THOMAS H. CONWAY, a citizen of the United States, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Ileating-Stovespf which the following is a specification, reference beingv had therein to the accompanyi11g.drawings.

This invention is in the nature of an attachment for heating-stoves of the well-known type in which the stove forms merely a combustion-chamber, the top being provided with a stovepipe connection and usually also with a boiler-hole; and the invention consists in the peculiar construction, arrangement, and operation of a baffle-plate adapted to fit into the stove below the top plate and form in connection therewith an indirect smoke-flue in the top of the stove, whereby the heating quality of the stove is improved at a slight cost, all as more fully hereinafter described, and shown in the drawings, in which Figure 1 is a vertical central section of a stove-top provided with my improvement. Fig. 2 is a vertical cross-section on line :10 at, Fig. 1. Fig. 3 is a detached perspective View of the baffle-plate. Fig. 4 is a horizontal section on line y y, Fig. 1, looking at the under side of the baffle-plate. Figs. 5, 6, and 7 are plan Views of modified forms of the baffleplate.

A is the body of the stove which forms the combustion-chamber.

B is the top plate.

0 is a boiler-hole in the top plate, D is the cover therefor, and E is the connection for the stovepipe, the parts representing the usual arrangement found in ordinary heating-stoves.

My invention consists in introducing below the top plate a baffle-plate E and there-.

by forming beneath the top plate an indirect smoke-flue F, where the stove is provided with the boiler-hole, as is the case in the stove shown in the drawings. I provide the baffle-plate with a circular standing flange G,which extends up to and joins to the boilerhole. This plate is provided with several apertures, whereby the combustion-chamber communicates into the smoke-fines above. One of these apertures, H,- is placed in directside of the stove, as in Fig. 3, or circuitous passages may be formed 011 top of the baffle plate by means of flanges or partitions K variously arranged, as shown in Figs. 5, 6, and 7, with which the openings communicate in the well-known manner to produce an indirect draft to the stovepipe. A preferable arrangement for operating the damper is shown in the drawings, wherein a is the shaft, to which the damper is secured in bearings formed in the depending flange b of the baffie-plate. One end of this shaft is formed with an upwardly-projecting crank c, which engages into a slot cl of a small plate 6, pivoted on top of the baffle-plate by means of socket-pin f, which has a squared aperture for the reception of the squared end of the loose 'crankhandle g, which projects upwardly through a hole in top of the stove. By making this crank-handle shorter or longer the construction is applicable to any stove to which the invention may be applied.

In practice it will be seen that by closing the damper I an indirect draft is provided, which greatly enhances the heating qualities of the stove, while by opening the damper I a direct draft is provided into the stovepipe. At the same time if the top is provided with the boiler-hole the convenience of the same is not interfered with. However, if it is not deemed necessary to provide the baffle-plate with a central opening communicating with the boiler-hole the arrangement shown in Fig. 5, wherein the indirect draft is concentrated in the center below the boiler-hole, may be suflicient. 1

What I claim as my invention is-=-- 1. The combination with a heating-stove wherein the body forms the combustionchamber and which is provided with a top and a stovepipe connection at or near the top, of a plate conformable to the horizontal section of the-body and located therein below the stove-top and stovepipe connection and dividing the stove into a lower combustion chamber and upper smoke-flue communicating directly with each other by means of two and located therein below the stove-top and dividing the stove into a lower combustionchamber and an upper smoke-flue communicating with each other directly by means of two apertures in said plate, a circular flange or partition surrounding a central opening in saidplate and extending to the stove-top and registering with the boiler-hole therein and forming an annular passage in the smoke-flue, one of said apertures in the plate being in direct-draft relation with the Stovepipe connection, and the other of said apertures being in indirect-draft relation with said Stovepipe connection, and a damper for the direct-draft aperture.

3. The combination with a heating-stove having a top provided with a central boilerhole, and a stovepipe connection, of a baffleplate E located within said stove below the top thereof and dividing the stove into an upper smoke-fine and a lower combustioncha1nber,an upwardly-extendin g circular partition above said plate forming an annular passage, said baffle-plate having an aperture J on one side of said partition and an aperture H 011 the other side of said partition below the stovepipe connection, and a damper for the aperture H.

4. The combination with a stove of a baffleplate therein having an aperture, a damper for said aperture, a crank c secured to said damper, a plate pivotally secured to said bailie-plate and provided with a slot in which said crank loosely engages, and an operatinghandle for said slotted plate detachably engaging the same and extending without the stove, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

THOMAS II. OONWVAY.
